Someone was asking for a RS-232 typewriter. I had one in 1978. I recently
found the negatives for photos of my SWTPC 6800 computer complete with an
IBM 2741 style Selectric printing terminal. It was used for letter quality
printing but it did have two way communication with my computer. I had to
write I/O drivers that converted ASCII to IBM Correspondence Code. I could
also use it over a 134.5 baud modem connection to a PDP11/70 timeshare
system.
I uploaded a picture to the Wikipedia Commons.

Here is a write up I did for the Northwest Computer News in July 1978.
